For some usecases it might eventually even replace JMS. This may have been because we're using an older version of SQL Server or because we have many database servers ). See, for example, the method signature for Connector#start: Once passed to the connector on startup, the provided properties can be parsed into more appropriate types by passing them to an instance of the AbstractConfig class provided by the Kafka Connect API. Each map in the List returned by taskConfigs corresponds with the configuration properties used by a task. A tag already exists with the provided branch name. Work fast with our official CLI. For example, I'm using JMS in my system and it should send messages to the other system that uses Kafka. There's always the option of having your web app be a Kafka producer itself, and ignore the lower level database stuff. Here is a sample implementation, which waits a certain number of milliseconds before querying the external source again for changes: Having implemented a monitoring thread that triggers task reconfiguration when the external source has changed, you now have a dynamic Kafka connector!
